Fujitsu have a number of wireless controllers. See this
link for some of the wireless interfaces.
However, there are other alternatives for the controlling of a Fujitsu unit via a third-party wireless interface. One of the common alternatives is to use Airzone Aidoo Wi-Fi or Aidoo Z-Wave Plus wireless interface (see this article for other Airzone's
interfaces).
See below image illustrating Airzone Aidoo and the wired controller connection to an AC unit.
For Aidoo Wi-Fi there are 2 common wireless interface that are compatible with most Fujitsu indoor units (either Floor/Ceiling, Split, Console, Ducted unit, or Cassette):
- AZAI6WSCFUJ

Important: This device is only compatible with 3 wires protocol Fujitsu
units equipped with the
UTY-RNNxM or
UTY-RSNxM thermostats. The
unit controller must remain working in parallel with your Aidoo as
“Master” mode.
- AZAI6WSCFU2
The connection for these Wi-Fi interfaces to the indoor units and configuring them to connect to the Wi-Fi router should be straightforward.

One advantage for the Aidoo Wi-Fi interfaces (check
AZAI6WSPMEL for Mitsubishi units) is that they support dual Wi-Fi communication unlike other wireless interfaces which only supports 2.4GHz alone. Again, there is an option for
BACnet/
Modbus integration.
Good to note, there some instances for some of the Fujitsu indoor units where an accessory may be required to integrate the Aidoo Wi-Fi interfaces (see table for sample units that require accessories).
